Front End Module Voltage Detection (VDET) Utility#

RAIL VDET Utility#

This optional software component can be enabled to include default functionality related to VDET configuration. VDET allows customers to measure a voltage during specific timestamps of a transmit packet. This information is used to tune FEM output power measurements during manufacturing and allows compensation for variability in the output path.

Configuration Options#

  • VDET mode

  • VDET resolution

  • VDET sample delay

The following hardware pin must be enabled to use VDET and is fixed to specific GPIO pins on supported EFR32 devices that cannot be changed.
